There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!

Answer:

x = 12

Step-by-step explanation:

18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.

Using this 3:4 scale factor we can find the missing side x.

Solving for x :

[tex]\frac{3}{4}[/tex] × 16 = 12

x = 12

OR: Set up a proportion:

[tex]\frac{24}{16}[/tex] × [tex]\frac{18}{x}[/tex]

cross-multiply

16 × 18 = 288

24 × x = 24x

288 = 24x

x = 12

Answer:

(-3,5)

Step-by-step explanation:

To solve using substitution, first isolate one variable in one of the given equations. Then, substitute the value you received from that equation for the matching variable in the second equation. Finally, substitute that value back into any of the equations to have both the x and y values.

1) The y in y = x + 8 is already isolated, so let's substitute that value for the y in x + y = 2. Substitute x + 8 for y in x + y = 2, then solve:

[tex]x + y = 2\\x + (x + 8) = 2 \\x + x + 8 = 2\\2x + 8 = 2 \\2x = -6\\x =-3\\[/tex]

Therefore, the x-value of the solution is -3.

2) Substitute the x value back into any of the one equations to find the value. Any choice is fine - in my work, I chose to substitute -3 for the x in y = x + 8:

[tex]y = x + 8 \\y = (-3) + 8\\y = -3 + 8\\y = 5[/tex]

Therefore, the y-value of the solution is 5.

3) Thus, the solution is (-3, 5).  

Answer:

C

Step-by-step explanation:

The common ratio (r) can be found as

r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex] → C

The common ratio of the geometric sequence is c. r = 3/2.

To determine the common ratio of a geometric sequence, we need to find the ratio between consecutive terms.

In the given sequence: 6, 9, 27 / 2, 81 / 4, ...

To find the ratio between consecutive terms, we divide each term by its preceding term.

9 / 6 = 3 / 2

(27 / 2) / 9 = 3 / 2

(81 /4 ) / (27 / 2) = 3 / 2

We observe that the ratio between consecutive terms is always 3 / 2.

Therefore, the common ratio of the geometric sequence is c. r = 3/2.

6 different ways

The number of different ways this can be done is 6 ways

Give the following students Hunter, Gavin, and Levi, line up one behind the other. They can line up in any form as they wish.

In order to line them up as they wish, we will take the factorial of the total student. In general;

n! = n(n-1)!

Since there are 3 students, the different ways can they stand in line is;

3! = 3 * 3 * 1

3! = 6

Hence the number of different ways this can be done is 6 ways

Answer:

x = 4[tex]\sqrt{3}[/tex]

y = 6

z = 8

Step-by-step explanation:

keep in mind I'm not doing that well with geometry so this might all be wrong lol

x is part of a 30 60 90 triangle.

so x is 4[tex]\sqrt{3}[/tex]

next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.

4 + 6 = 10

10^2 = 100

100 = a^2 + b^2

y = 6 and z = 8 bc 36 + 64 = 100

Answer:

2 games

Step-by-step explanation:

Given data

The Fun Guys game

charges  annual fee of  $5 plus $5.50 per game

let the number of games be x

and the total charges be y

The expression for the total is

y=5+5.5x---------------1

The Game Bank

charges an annual fee of $11 plus $2.50 per game.

y=11+2.5x---------------2

Equate 1 and 2 above

5+5.5x=11+2.5x

collect like terms

5.5x-2.5x= 11-5

3x= 6

divide both sides  by 3

x= 6/3

x= 2

It will take 2 games

Yes it is showing a function

Step-by-step explanation:

Given;

The graph of a line.

To find:

The slope of the line.

Solution:

From the given graph it is clear that the line passes through the points (1,7) and (3,5).

So, the slope of the given line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{5-7}{3-1}[/tex]

[tex]m=\dfrac{-2}{2}[/tex]

[tex]m=-1[/tex]

Slope of the line is -1.

Therefore, the correct option is D.

Answer:

The retail price to purchase a remote-controlled car at the hobby store is $42

Step-by-step explanation:

Original Price of remote controlled car = $35

Mark up = 20%

We need to find retail price.

First we will find mark up value i.e. 20% of 35 and then add it to the original price to find retail price.

Finding 20% of 35

[tex]20\% \:of\: 35\\=\frac{20}{100}\times 35\\=7[/tex]

So, mark up price is $7

Now, the retail price will be:

Retail price = Original Price + Mark up

Retail price = 35 + 7

Retail price = 42

So, the retail price to purchase a remote-controlled car at the hobby store is $42

Answer:

see explanation

Step-by-step explanation:

Note that [tex]log_{e}[/tex] x = lnx ( natural logarithm)

Using the standard derivatives

[tex]\frac{d}{dx}[/tex] (lnx ) = [tex]\frac{1}{x}[/tex] , [tex]\frac{d}{dx}[/tex] ([tex]log_{a}[/tex] x ) = [tex]\frac{1}{xlna}[/tex]

Using the chain rule

Given y = f(g(x)) , then

[tex]\frac{dy}{dx}[/tex] = f'(g(x))) × g'(x) ← chain rule

(c)

y = [tex]log_{10}[/tex] (x² - 2) then

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{(x^2-2)ln10}[/tex]  × [tex]\frac{d}{dx}[/tex] (x² - 2)

    = [tex]\frac{1}{(x^2-2)ln10}[/tex] × 2x

    = [tex]\frac{2x}{(x^2-2)ln10}[/tex]

(d)

y = ln([tex]\frac{1}{x}[/tex] )

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{\frac{1}{x} }[/tex] × [tex]\frac{d}{dx}[/tex] ([tex]x^{-1}[/tex] )

   = x × - [tex]x^{-2}[/tex]

   = x × [tex]\frac{-1}{x^2}[/tex]

   = - [tex]\frac{1}{x}[/tex]
